Application of transcranial direct current stimulation in cricopharyngeal dysfunction with swallowing apraxia caused by stroke: A case report

RATIONALE: Dysphagia is a common complication after stroke. The 2 types of dysphagia with cricopharyngeal dysfunction and swallowing apraxia after stroke are relatively rare and difficult to treat; however, there are few clinical case reports of cricopharyngeal dysfunction and swallowing apraxia after stroke. PATIENT CONCERNS: A case of cricopharyngeal dysfunction and swallowing apraxia due to cerebral infarction caused by atrial fibrillation in a 63-year-old woman who was followed up for 1 year. DIAGNOSES: The patient was diagnosed with cricopharyngeal dysfunction and swallowing apraxia caused by stroke based on the clinical course and imaging findings. INTERVENTIONS: Pharmacotherapy and rehabilitation therapy. OUTCOME: The patient's swallowing function returned to normal, and her nasal feeding tubes were removed, and oral feeding was resumed. LESSONS: The 2 types of dysphagia with cricopharyngeal dysfunction and swallowing apraxia after stroke are relatively rare and difficult to treat after stroke. Only by improving swallowing apraxia can patients perform mandatory swallowing and balloon dilatation treatment. However, transcranial direct current stimulation has a good therapeutic effect on the primary motor and sensory cortex of the tongue in patients with cricopharyngeal dysfunction and swallowing apraxia.
